METER.

SPECIFICATION forming part of Letters Patent No. *766,535, dated August2, 1904. Application filed April 5, 1904. Serial No. 201,(332. (Nomodel.)

To all whom it may concern:

Be it known that I, XVILLIAM R. SHARP, a citizen of the United States,residing at New Philadelphia, in the county of Tuscarawas and State ofOhio, have invented certain new and useful Improvements in Meters; and Ido hereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the annexed drawings,making a part of this specification, and to the numerals of referencemarked thereon.

The object oi' the present invention is to provide a meter that willmeasure the water of condensation in' pounds or liquid measure, therebymeasuring the amount of steam employed or used for heating purposes.

Figure 1 is a Vertical horizontal section. Fig. 2 is a perspective viewof the drip or dump- 'ing pan, showing the casing removed andillustrating the water-of-condensation spout in proper relativeposition, also showing the catch-trough. Fig. 3 is a transverse sectionof one of the Vertical sides of the casing, showing an edge view of themeter ratchet-Wheel and casing, also showing a partial end view of thedumping-pan.

Similar numerals of reference indicate corresponding parts in all thefigures of the drawings.

In the accompanyng drawings, 1 represents the casing, which may be ofany desired size, and in which casing is'located the dumpingpan 2, saiddumping pan being pvotally mounted upon the fulcrum-rib 3, and for thepurpose of preventing friction said fulcrumrib is provided with acomparative sharp edge, which sharp edge rests in the notches 1, formedin the supports 5, which supports are fixed to 'the casing in anyconvenient and well-known manner. The dumping-pan 2 is so formed andmounted that its normal position will be that shown in Fig. 2 and infull lines, Fig. 1.

For the purpose of stopping or holding the dumpingpan in proper positionthe stopscrew 6 is provided, said stop-screw being so located that thebottom or under side of the dumping-pan will strike the top or upper endof the screw 6, as illustrated in Fig. 1.

From the radiator or radiators leads the water-of-condensation pipe 7,and upon the inner face of the casing and opposite the pipe '7 islocated the discharge-pipe section 8, which pipe is curved, asillustrated in the drawings, and provided with anelongated outlet 9,said pipe 8 being curved for the purpose of better conducting the waterinto the dumping-pan 2 and into the temporarily -holding waterpan 10.

To the dumping-pan 2 is pivotally attached the detent 11, which detentis so formed that when the dumping-pan is in a tilted position, asillustrated in dotted lines, Fig. 1, said detent Will engage one oftheteeth 12, 'o'med upon the meter-ratchet 13, and after the watercontained in the dumping-pan has escaped therefrom said dumping-pan willassume its normal position, and in assuming its normal position thedetent 11 will move downward with the dumping-pan, thereby turning theratchet-wheel 13, said ratchetwheel being provided with a predeterminednumber of teeth, so as to give the ratchet-wheel 13, together with themeter-shaft 14, the desired part of a revolution, the most convenientdivision being one-tenth of a revolution to each downward tilt of thedumping-pan at the dctent end thereof.

It Will be understood that in order to provide for the automatic tiltingof the dumpingpan when empty it must be so balanccd that the greaterWeight of the dumping-pan will be upon the end provided with the detent11; but when a certain quantity of water is conveyed to the dumping-panthe greater weight Will be upon the opposite end of the dumpingpan fromthat to which the detent is attached, thereby causing the dumping-pan totilt into the position illustrated in dotted lines, Fig. 1, and When inthat position the water will escape or run from the dumping-pan.

It will be understood that owing to the fact that a certainpredetermined amount of Water must be contained in the dumping-panbefore it is tilted the meter proper will register the number of tilts,thereby providing a means for calculating the amount of condensed waterthat has passed through the pipe 7 and from thence through thedumping-pan and out the discharge-pipe 15.

The mechanism or train of wheels employed IOO in a meter is not hereillustrated, owing to the fact that they form no particular part of thepresent invention, except that a meter operated by the ratchet-wheel 13and the detent 11' is to be employed.

For the purpose of stopping the tilting movement of the dumping-pan atthe time it is desired to discharge the water therefrom the stop-screw16 is employed, which stopscrew is so adjusted that when the deliveryend of said dumping-pan comes in cantact with the top or upper end ofsaid stop-screw it Will have the proper incline to permit the water tobe discharged from said dumpingpan.

It is well understood that during the time various radiators are filledwith steam the water of condensation is continuously flowing, and inorder to prevent any water from escaping the dumping-pan during the timeit is being emptied the pivoted trough or receptacle 10 is employed,which trough is so located that its normal position will be that shownin Figs. 1 and& which position permits the water to flow from the trough17 into the dumping-pan 2; but during the time said dumping-pan is inthe position illustrated in dotted lines, Fig. 1, the trough orreceptacle will be in the position illustrated in dotted lines, Fig. 1,said position being such that the water will be confined in saidreceptacle, and when the dumping-pan assumes its normal position thereceptacle 17 will fall by gravity into the position illustrated inFig.-1, thereby allowing the water which has accumulated in the troughduring the time the dumping-pan is being emptied to flow from saidreceptacle 17 into the dumping-pan, by which ari-angement all the waterof condensation is measured and none escapes or passes through the pipe15 that has not passed over the dumping-pan 2.

In order to reduce the t'riction and to allow the easy movement of thedumping-pan and the receptacle 17, the antifriction-roller 18 isprovided, which antifriction-roller is so located that as the detent endof the dumpingpan is elevated theroller 18 will come in contact with thebottom or under side of the receptacle 10.

It will be understood that the receptacle 10 should be pivoted a shortdistance to one side o' its longtudinal center, thereby providing ameans for the automatic tilting of said receptacle when not engaged withthe roller 18.

By the use of the dumping-pan 2 and operatively connecting saiddumping-pan with a meter mechanism the amount of steam can be measuredthat has passed through a radiator or any given number of radiators thecondensation-pipes of which are so connected that all of the water ofcondensation will be delivered to the dumping-pan, by which arrangementI am enabled to provide a means for actually determining the amount ofsteam employed to heat any particular building or any room of abuilding.

If in the event a heating system is employed to heat a number ofbuildings or difierent places, it will be understood that a meter suchas illustrated can be employed for each building or room, if desired,this being very desirable where a central plant or a bank of boilers isemployed to furnish heat for city use or for other places Wherein theheat is to be distributed to various places.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The combination of a casing, a dumpingpan located therein andprovided with a fulcrum-rib, a support for said rib and pan the pannormally located at an angle to a horizontal plane, a detent pivotallyattached to the dumping-pan, and a ratchet-wheel adapted for engagementwith the detent, a receptacle located over the infiow end of thedumping-pan and pivoted at one side of its gravity center, adjustablestops adapted to limit the movements of the dumping-pan, and aregistering device operated by said ratchet-wheel, substantially as andfor the purpose specified.

2. The combination of a casing, a dumpingpan located therein andpivotally mounted between its ends, said pan normally located at anangle to a horizontal plane, a detent pivotally attached to the infiowend of the dumping-pan and a ratchet-wheel for eng-agement with thedetent, an antifriction-roller connected to the dumping-pan and carriedthereby, a receptacle located over the infiow end of the dumping-pan andpivoted at one side of its gravity center, means for limiting thetilting of the dumping-pan, and a registering device operated by saidratchet-wheel, substantially as and for the purpose specified.

In testimony that l claim the above I have hereunto subscribed my namein the presence of two witnesses.

WILLIAM R. SHARP.
